Misfit's bargain Flash fitness tracker has been treated to some fancy jewellery cases from fashion brand BaubleBar. The two new styles - the Helena Bracelet and the Helena Necklace - will go on sale exclusively at Target in the US from 29 November.

Each of the BaubleBar for Misfit accessories, as they are being sold, encloses the circular tracker in a 'locket'. So you won't be able to see the LEDs on the top of the device to show the time or your activity progress. Each locket is on an oval-link chain - of an unspecified material. It's a 32-inch chain on the Helena Necklace and 6 inches for the bracelet.

The bundles cost $69.99 each and include an activity claps and a sport band in fuschia as well as the bracelet or necklace, so you can switch between the cases and accessories. The Flash alone is currently going for $29.99 in the US.

This Misfit collaboration is hot on the heels of Jawbone teaming up with BaubleBar to prettify its UP Move tracker. But it's nice to see that the Flash is getting some fashion love as Misfit has focused on partnerships for its Shine tracker, like the Swarovski Shine.

This deal has probably be in the works for a while. Fossil has just announced it is buying Misfit for $260 million so it's unlikely now we will see any more Misfit branded fashion collaborations. Sonny Vu will have access to all the fashion and brand power of Fossil when he takes up his role as chief technology officer of connected devices.
